I have a weird issue of getting alert after 4 hours of the event. Logs in the device sending syslog has correct time. When i query in sumo, i see the event happened for example at 2 pm while the event actually happened at 10 AM in the morning which is 4 hours earlier. However, if i check r"use receipt time" in sumo query dashboard, i do see the logs at actual time. So, how do i generate alert with checked "use receipt time"?

  Hi There - this is likely a timezone issue. If you navigate to your collector management page (Manage Data > Collection) you will need to correct the syslog source's timezone by adjusting it to the timezone of the physical location those syslog messages are being generated in.
  
  Here is a screenshot for where to adjust:
  
  
  I hope this helps, let us know if you have additional questions here.
  
  Thanks,

  Even I am facing the same problem regarding time lag even after time zone modification. It is taking 20-30 minutes to reflect the logs in the dashboard. Is this time can be reducible?

  Hey Anil,
  
  There are many reasons data might be delayed getting to Sumo Logic. What type of log is this?
  
  Here's a query you can try to see the difference between when the event was generated and when we received it:

  _sourceCategory=<Your_Category_here>

  | ((_receipttime - _messagetime)/1000)/60 as timediffmins
  | timeslice 5m
  | avg(timediffmins) by _timeslice
